Description

Spray product

Technical Field

The present invention relates to a valve unit having a core tube protruding from an aerosol container and an actuator fitted in the core tube, and more particularly to an aerosol product suitable for ejecting a content in a foam state.

Background

There is known an aerosol product including a valve unit having a core tube protruding from an aerosol container and an actuator fitted in the core tube, and there is also known an aerosol product in which the contents in the container are discharged from the actuator in a foam state.

For example, patent document 1 describes a spray product (foamable spray product 10) having: a pressure-resistant spray container (outer container 11); a storage space (inner container 12) which is stored in the aerosol container (outer container 11) and which is provided with a partition wall having a variable volume; a valve unit (aerosol valve 13) that communicates with the housing space (inner container 12); a foamable composition which is filled in the storage space (inner container 12) and contains a foamable liquid (aqueous stock solution) and a foaming agent (lipophilic liquefied gas); and a pressurizing agent B filled in the pressurizing chamber S between the housing space (inner container 12) and the aerosol container (outer container 11).

The aerosol product (foamable aerosol product 10) can maintain a gas phase in the storage space (inner container 12) by setting the pressure of the pressure agent B to be equal to or lower than the pressure of the foamable composition and higher than the atmospheric pressure, and can form a uniform foamable liquid (aqueous stock solution) and a dispersed phase of a foaming agent (lipophilic liquefied gas) by vertically shaking the aerosol container (outer container 11) to emulsify the foamable composition, and can discharge a foam in a stable state.

Further, although the gas phase portion in the housing space (inner container 12) is communicated with the atmosphere during use, and a part of the gas in the gas phase portion in the housing space (inner container 12) may be immediately released into the atmosphere after use, the pressure in the housing space (inner container 12) is reduced at the same time, and therefore, the housing space (inner container 12) is contracted by the pressure of the pressurizing agent B, and becomes a nearly liquid-tight state. Thus, even if the spray product (foamable spray product 10) is discharged in the upright or inverted state, the liquid phase portion in the storage space (inner container 12) can be reliably discharged.

Further, it is also possible to accommodate 2 accommodation spaces (inner container 12) in one aerosol container (outer container 11), and it is also possible to provide an aerosol product (foamable aerosol product 10) which can be ejected simultaneously or separately as foams from 2 foamable compositions in a compact size.

Disclosure of Invention

However, the spray product known from patent document 1 still has room for improvement.

That is, in the case of a spray product in which the foamable liquid and the foaming agent are separately present in the same inner container in a state in which the spray product is left to stand, it takes time to shake the spray product before use to emulsify the spray product, and in the case where the spray product is left to stand without being discharged after shaking, depending on the nature of the foamable liquid, the gas phase portion in the inner container may be filled with foam, and if the foam cannot be removed until the next use, there is a fear that the foamable liquid and the foaming agent cannot be sufficiently emulsified even by shaking the spray product again.

Further, depending on the type of the foamable liquid, the foamable liquid may be deteriorated or its properties may be changed due to contact with the foaming agent, and therefore, both the foamable liquid and the foaming agent may not be contained in 1 inner container.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a spray product having a simple structure, in which a foamable liquid and a foaming agent are not brought into contact with each other in a spray container during storage, and the foamable liquid and the foaming agent can be sufficiently emulsified without shaking the spray container to discharge a good foam.

The spray product of the present invention comprises: a valve unit having a core tube protruding from the aerosol container; and an actuator fitted to the core tube, wherein the aerosol container includes: a plurality of divided accommodating spaces; an inflow port corresponding to the accommodation space; and 1 or more valve units each having a sealing member for opening and closing each of the inlets, wherein at least one of the plurality of storage spaces is a foamable liquid storage portion for storing a storage material containing a foamable liquid, and at least one of the other storage spaces is a foaming agent storage portion for storing a storage material containing a foaming agent, and the valve units are configured such that: the above problem can be solved by mixing the foamable liquid discharged from the inlet port corresponding to the foamable liquid containing portion and the foaming agent discharged from the inlet port corresponding to the foaming agent containing portion in the actuator.

According to the spray product of the invention according to claim 1, the spray container includes: a plurality of divided accommodating spaces; an inflow port corresponding to the accommodation space; and 1 or more valve units each having a sealing member for opening and closing the inflow opening, wherein at least one of the plurality of housing spaces is a foamable liquid housing section for housing a housing containing a foamable liquid, and at least another one of the plurality of housing spaces is a foaming agent housing section for housing a housing containing a foaming agent, and the valve units are configured such that: the foamable liquid discharged from the inlet port corresponding to the foamable liquid containing portion and the foaming agent discharged from the inlet port corresponding to the foaming agent containing portion are mixed in the actuator, and therefore, even if the foamable liquid and the foaming agent react and change in quality due to the mixing with each other, they can be stored in a state of being separated from each other until immediately before use.

Further, since the foamable liquid and the foaming agent are mixed in the actuator, the mixture can be discharged in a foam state without shaking the container until just before use.

According to the structure described in claim 2, the inlet port corresponding to the foaming agent storage portion is configured to: since the liquid phase of the foaming agent is discharged from the foaming agent containing portion, the liquid phase of the foaming agent and the foamable liquid can be reliably mixed in the actuator and discharged in a foam state without discharging the gas phase of the foaming agent.

According to the structure described in claim 3, the spray container includes: the foaming agent container includes 1 container and 1 or more foamable liquid container portions housed in the container, and the foaming agent container portion is constituted by a space outside the foamable liquid container portion in the container, and therefore, the foaming agent can be ejected by pressing the foamable liquid container portion with the pressure of the gaseous phase of the foaming agent, and it is not necessary to prepare a gas for ejection other than the foaming agent.

According to the structure described in claim 4, the actuator includes: a fitting portion fitted in the core tube; a mixing section for mixing the ejecta from the inlet; and an ejection port for ejecting the mixed ejection product, wherein the foamable liquid and the foaming agent are first merged and mixed in an actuator provided at the tip of the valve unit, and therefore, even when residual liquids of the foamable liquid and the foaming agent mixed in the actuator adhere, it is possible to maintain good foamy ejection only by replacing or cleaning the actuator.

In addition, by replacing the actuator of a different shape, the state of the discharged foam can be changed.

Detailed Description

Hereinafter, a spray product 100 according to an embodiment of the present invention will be described with reference to the drawings.

Specific applications of the foamable liquid of the present invention include a cleansing agent, a shaving agent, a hair growth agent, a hand sanitizer, a setting agent, and the like, and examples of the compositions thereof are shown in tables 1 to 6.

The use and composition of the foamable liquid usable in the present invention are not limited to these.

[ Table 6]

As shown in fig. 1, the aerosol product 100 is a so-called double-valve type product, and 2 valve units 120 are fixed to the mouth of the aerosol container 110 by a chevron cup 111, and 2 core tubes 121 protrude upward.

The storage space in the spray container 110 is divided into: the foam liquid container includes 2 storage spaces, namely a flexible foamable liquid storage section 141 and a foaming agent storage section 140 located outside the foamable liquid storage section 141.

The foamable liquid containing portion 141 contains a container S containing a foamable liquid in a dense state, and the foaming agent containing portion 140 contains a foaming agent LG.

An inlet 122 for communicating the inside and the outside of the valve unit 120 is provided at the lower part of the valve unit 120, one of the 2 valve units 120 is connected to the inlet 122 so as to discharge the contents S inside the foamable liquid containing section 141, and the other valve unit 120A (hereinafter, referred to as "liquid phase valve unit 120A") is configured to: the hollow dip tube 143 is connected to the inlet 122 so as to discharge the liquid phase portion of the foaming agent LG contained in the foaming agent containing portion 140.

The core tube 121 projecting upward from the 2 valve units 120 has a seal member 123, the actuator 130 is attached to the core tube 121 via a fitting portion 132, and the discharge flow path 133 provided in the actuator 130 is configured to: the 2 core tubes 121 are connected to each other, and the contents S and the blowing agent LG are merged and then discharged from the discharge port 131.

Next, the foam-like discharge of the contents S and the foaming agent LG by the spray product 100 will be described.

First, by pressing the actuator 130 downward, the sealing member 123 releases the closing of the flow path in the inflow port 122 and the core tube 121, whereby the valve unit 120 and the liquid phase valve unit 120A are opened, and the liquid phase portion of the foaming agent LG is discharged from the core tube 121 through the dip tube 143 by the pressure of the gas phase portion of the foaming agent LG contained in the foaming agent containing portion 140, and the foamable liquid containing portion 141 is also subjected to the pressure to discharge the contained substance S from the core tube 121.

The blowing agent LG and the contained substance S merge in the discharge flow path 133 in the actuator 130.

At this time, the blowing agent LG and the contents S are vigorously collided and mixed in the discharge flow path 133 by the pressure of the gas phase portion of the blowing agent LG.

Thus, the contained substance S and the foaming agent LG can be emulsified without shaking the spray container 110.

Further, since the foaming agent LG is gradually vaporized and expanded in an emulsified state to generate numerous fine bubbles, the content S can be discharged in a foam form from the discharge port 131 of the actuator 130.

In addition, in the present embodiment, the configuration is such that: the remaining amount reducing member 142 is attached to the inlet 122 in the foamable liquid storage section 141, and the amount of the discharged content S is stabilized and the remaining amount is reduced until the end.

Since the contained substance S is discharged by the pressure applied from the foaming agent containing portion 140 to the foamable liquid containing portion 141, the contained substance S and the foaming agent LG do not come into contact with each other during storage, and it is not necessary to mix materials for applying pressure to the contained substance S.

Further, when the foaming agent LG is a low-pressure foaming agent and the foaming agent LG and a compressed gas as a propellant are filled in the foaming agent housing portion 140, a rapid increase in pressure can be suppressed even in a high-temperature state, as compared with a case where the foaming agent LG is also used as a propellant.

Further, since the content S and the foaming agent LG can be stored in a separated state by the foamable liquid containing portion 141, even if the content S and the foaming agent LG are mixed and reacted or deteriorated, they can be stored without being mixed with each other until immediately before use.

Further, since the contained substance S and the blowing agent LG are first merged in the actuator 130, even when the remaining liquid of the contained substance S and the blowing agent LG adheres to the actuator 130 after the discharge and blocks the discharge flow path 133, the favorable foam-like discharge can be maintained again only by replacing or cleaning the actuator 130, and the state of the discharged foam can be easily changed by replacing the actuator 130 with a different shape of the discharge flow path 133.

Next, a spray product 200 according to another embodiment of the present invention will be described with reference to the drawings.

Note that description of the components common to the spray product 100 is omitted.

As shown in fig. 2, the aerosol product 200 is provided with a flexible foamable liquid containing portion 242 and a flexible foaming agent containing portion 241 in the containing space in the aerosol container 210, and further provided with an injection agent containing portion 240 outside the foamable liquid containing portion 242 and outside the foaming agent containing portion 241, and the interior of the aerosol container 210 is divided into 3 containing spaces.

The expandable liquid storage portion 242 contains a storage material S containing an expandable liquid in a dense manner, and the foaming agent storage portion 241 contains a foaming agent LG for foaming the expandable liquid in a dense manner.

The propellant storage unit 240 stores the propellant B, and the propellant B applies pressure to compress the foamable liquid storage unit 242 and the foaming agent storage unit 241 when being discharged.

Accordingly, the foaming agent LG in the foaming agent containing portion 241 does not need a pressure for ejecting the content S in the foamable liquid containing portion 242, and a low-pressure foaming agent LG can be used, and the propellant B in the propellant containing portion 240 can be contained so as to maintain a sufficiently higher pressure than the foaming agent LG, so that a gas phase portion is hardly generated in the foaming agent LG in the foaming agent containing portion 241, and a liquid-tight state can be maintained in the foaming agent containing portion 241.

Further, although a gas phase may be generated in the blowing agent storage portion 241 by the pressure difference between the blowing agent B and the blowing agent LG, in this case, a liquid phase portion may be sucked by using a dip tube or the like.

An inlet port 222 for communicating the inside and the outside of the valve unit 220 is provided at the lower part of the valve unit 220, one of the 2 valve units 220 is connected to the inlet port 222 so as to discharge the contents S inside the foamable liquid containing section 242, and the other valve unit 220A (hereinafter, referred to as "liquid phase valve unit 220A") is configured to: the blowing agent LG contained in the blowing agent containing portion 241 connected to the inlet 222 is discharged.

Next, the foam-like discharge of the contents S and the foaming agent LG by the spray product 200 will be described.

First, by pressing the actuator 230 downward, the sealing member 223 releases the sealing of the flow path in the inflow port 222 and the core tube 221, so that the valve unit 220 and the liquid phase valve unit 220A are opened, and the foamable liquid containing portion 242 and the foaming agent containing portion 241 are subjected to the pressure of the propellant B contained in the propellant containing portion 240, and the liquid phase portion of the contained substance S and the foaming agent LG is discharged from the core tube 221.

The blowing agent LG and the contained substance S merge in the discharge flow path 233 in the actuator 230.

At this time, the blowing agent LG and the content S are vigorously collided and mixed in the discharge flow path 233 by the pressure of the propellant B.

Thus, the contained substance S and the foaming agent LG can be emulsified without shaking the spray container 210.

Further, since the foaming agent LG is gradually vaporized and expanded in an emulsified state to generate numerous fine bubbles, the contained material S can be discharged in a foam state from the discharge port 231 of the actuator 230.

In addition, in the present embodiment, the configuration is such that: the remaining amount reducing member 243 is attached to the inlet 222 in the foamable liquid containing section 241, and stabilizes the discharge amount of the contained substance S and reduces the remaining amount until the end.

In addition, in the case where the propellant B is composed of a liquefied gas, even if the pressure of the gaseous phase portion of the propellant B is reduced by ejecting the contained material S and the foaming agent LG, the liquid phase portion of the propellant B vaporizes to compensate for the pressure of the propellant B, and therefore, the ejection pressure of the contained material S and the foaming agent LG can be prevented from being reduced.

In addition, when the blowing agent LG is a low-pressure blowing agent and the propellant B is made of a compressed gas, a rapid increase in pressure can be suppressed even in a high-temperature state, as compared with the case of using a liquefied gas as a propellant.

Here, as for the kind of gas used as the foaming agent and the propellant, a known liquefied gas and compressed gas used in spray products can be generally used.

Examples of the type of liquefied gas used as the blowing agent and the propellant include propane, butane, pentane, liquefied petroleum gas containing propane, butane, pentane, dimethyl ether, hydrofluoroolefin, and hydrofluorocarbon, and examples of the type of compressed gas used as the blowing agent and the propellant include nitrogen, carbon dioxide, compressed air, oxygen, helium, and nitrous oxide, and these gases can be used by mixing them.

Although the embodiments of the present invention have been described above in detail, the present invention is not limited to the above embodiments, and various design changes can be made without departing from the present invention described in the claims.

In the above-described embodiment, the configuration in which the remaining amount reducing member is attached to the inflow port has been described, but the configuration in the foamable liquid containing portion is not limited to this, and for example, the remaining amount reducing member may not be provided, and a dip tube may be attached so that a gap can be formed in a part of the inflow port.

In the above-described embodiment, the so-called two-valve type in which 2 valve units are provided in 1 aerosol container has been described, but the configuration of the present invention is not limited to this, and for example, the number of valve units may be 3 or more, a plurality of housing spaces may be configured in a plurality of aerosol containers having 1 valve unit, and a plurality of inflow ports and seal members corresponding to the plurality of inflow ports may be provided for 1 valve unit.

In the above-described embodiment, the structure for ejecting the liquefied gas from the liquid phase valve unit has been described, but the structure for ejecting the liquefied gas from the liquid phase valve unit is not limited to this, and for example, a fragrance component that is not separated from the liquefied gas may be mixed with the liquefied gas.

In the above embodiment, the following description is made: the liquid phase valve unit is configured as a liquid phase portion that is connected to the hollow dip tube and discharges the liquefied gas contained in the foaming agent storage portion, but the method of discharging the liquefied gas is not limited to this, and for example, the dip tube may be disconnected and the spray container may be discharged in an inverted state, or a weight may be attached to the tip of the dip tube made of a flexible material, and the tip of the dip tube may be always located below the liquid level of the liquefied gas regardless of the orientation of the spray container, thereby sucking the liquid phase of the liquefied gas.

In the above embodiment, the following description is made: the foaming agent and the content are mixed by being vigorously collided in the discharge flow path by the pressure of the gas phase portion of the foaming agent, and thus the content and the foaming agent can be brought into an emulsified state without shaking the spray container.
